The question asked, verbatim: best application performance monitoring for agencies

Brands named, in the order the engine gave

1. Sentry mentioned
   Sentry - my default pick for most agencies.
2. Site24x7 mentioned
   Site24x7 MSP Edition - the only mainstream platform genuinely built for the agency/MSP shape instead of adapted to it.
3. Site24x7 MSP Edition mentioned
   Site24x7 MSP Edition - the only mainstream platform genuinely built for the agency/MSP shape instead of adapted to it.
4. APM mentioned
   APM Insight covers Java, .NET, PHP, Ruby, and Node.
5. Ruby mentioned
   APM Insight covers Java, .NET, PHP, Ruby, and Node.
6. New Relic mentioned
   New Relic - best free/cheap tier for a long tail of small client apps: 100GB/month ingest with full APM, though only 1 full platform user.
7. Datadog mentioned
   Datadog - reach for it when a specific client is big enough to pay for it directly.
8. Grafana Cloud compared
   At ~100 hosts with APM and logs it runs roughly $5,500/mo versus ~$300-800 for Grafana Cloud Pro - so put it in the client's name and on the client's card, never your agency's.
9. Grafana Cloud + OpenTelemetry mentioned
   Grafana Cloud + OpenTelemetry - the anti-lock-in play, and what I'd choose if you want one instrumentation standard across every client codebase.
10. OpenTelemetry mentioned
    Grafana Cloud + OpenTelemetry - the anti-lock-in play, and what I'd choose if you want one instrumentation standard across every client codebase.
11. AppSignal mentioned
    AppSignal or Scout Monitoring - flat, predictable per-app pricing for Rails/Laravel/Node/Elixir shops.
12. Better Stack mentioned
    Better Stack - pair with any of the above for uptime plus client-facing status pages, included rather than sold separately.
13. Checkly mentioned
    Checkly - if you write Playwright tests, this turns them into synthetic monitors and CI/CD deploy gates.
14. Raygun mentioned
    Raygun - crash reporting plus real-user monitoring with report output clients actually understand.
15. WordPress mentioned
    If you're a WordPress or marketing-site agency, skip real APM for most sites: ManageWP, InstaMonitor, or Watchman Tower for bulk uptime/performance/SSL across client sites, with New Relic or your host's APM reserved for the one or two sites with custom code.

The answer, as recorded

## What I'd actually recommend, in order **1. Sentry** - my default pick for most agencies. Pricing is volume-based rather than per-host or per-seat, so a dozen small client apps cost almost nothing; errors, tracing spans, session replay, logs, and uptime all meter separately against one budget. Team is ~$26/mo, Business ~$80/mo, each with 50k errors and 5M spans included. The agency-specific win: one org per client, and when the engagement ends you transfer the org to the client instead of untangling your account. Watch tracing spans - at roughly $1.60-$4.00/M they dominate overages, so sample aggressively.

Site24x7 MSP Edition** - the only mainstream platform genuinely built for the agency/MSP shape instead of adapted to it. Multi-tenant by design: unlimited customer accounts, single login across all of them, role-based access per client, NOC view, and real white-labeling (your logo, name, custom URL on dashboards *and* reports). APM Insight covers Java, .NET, PHP, Ruby, and Node. If you bill clients for monitoring as a line item, this is the one that makes that look professional.

New Relic** - best free/cheap tier for a long tail of small client apps: 100GB/month ingest with full APM, though only 1 full platform user. Ingest-metered at ~$0.40/GB rather than per-host, which suits agencies running many low-traffic apps. The single-user limit is the catch - fine for a small team, painful once several engineers need deep access. [monitoringcost.com/apm-pricing-comparison](https://monitoringcost.com/apm-pricing-comparison) · [atatus.com/blog/new-relic-alternatives](https://www.atatus.com/blog/new-relic-alternatives) **4. Datadog** - reach for it when a specific client is big enough to pay for it directly. Broadest integration coverage, multi-org account structure, APM around $31-35/host/mo plus indexed spans. At ~100 hosts with APM and logs it runs roughly $5,500/mo versus ~$300-800 for Grafana Cloud Pro - so put it in the client's name and on the client's card, never your agency's. [costbench.com/software/observability/datadog/alternatives](https://costbench.com/software/observability/datadog/alternatives/) · [monitoringcost.com/apm-pricing-comparison](https://monitoringcost.com/apm-pricing-comparison) **5. Grafana Cloud + OpenTelemetry** - the anti-lock-in play, and what I'd choose if you want one instrumentation standard across every client codebase. Instrument with OTel once, point it at Grafana Cloud (Pro ~$19/mo base + usage; traces ~$0.45-0.50/GB), and if a client later wants Datadog or self-hosting, you repoint the collector instead of rewriting. Separate stacks give you clean per-client isolation. Costs you setup effort versus the turnkey options.

AppSignal or Scout Monitoring** - flat, predictable per-app pricing for Rails/Laravel/Node/Elixir shops. Scout has a genuinely free tier (300k transactions) and goes $19 → $39 → $99/mo; AppSignal starts around $23 with excellent support reputation. Easiest thing to quote to a client as a fixed monthly cost. [scoutapm.com/blog/best-apm-for-small-teams-in-2026](https://www.scoutapm.com/blog/best-apm-for-small-teams-in-2026) · [g2.com/compare/appsignal-vs-scout-monitoring](https://g2.com/compare/appsignal-vs-scout-monitoring) **7. Better Stack** - pair with any of the above for uptime plus client-facing status pages, included rather than sold separately. Starts ~$9/mo. Good incident workflows for on-call retainers. [betterstack.com/community/comparisons/better-stack-vs-checkly](https://betterstack.com/community/comparisons/better-stack-vs-checkly/) **8. Checkly** - if you write Playwright tests, this turns them into synthetic monitors and CI/CD deploy gates. ~$24/mo up; status pages are a separate $9-30/mo plan. Strongest fit when you own the client's deploy pipeline. [betterstack.com/community/comparisons/better-stack-vs-checkly](https://betterstack.com/community/comparisons/better-stack-vs-checkly/) **9. Raygun** - crash reporting plus real-user monitoring with report output clients actually understand. $60/mo entry, no free plan, so it's a deliberate choice rather than a default. [capterra.com/p/159822/Raygun](https://capterra.com/p/159822/Raygun/) **10. If you're a WordPress or marketing-site agency**, skip real APM for most sites: ManageWP, InstaMonitor, or Watchman Tower for bulk uptime/performance/SSL across client sites, with New Relic or your host's APM reserved for the one or two sites with custom code. [instawp.com/wordpress-uptime-monitoring-3-easy-ways-for-agencies](https://instawp.com/wordpress-uptime-monitoring-3-easy-ways-for-agencies/) · [belovdigital.agency/performance-monitoring-stack](https://belovdigital.agency/performance-monitoring-stack/) **The stack I'd build:** Sentry for application-level errors and tracing across every client, Better Stack for uptime and status pages, and Site24x7 MSP underneath if white-labeled client reporting is part of what you sell. Add Datadog only per-client, on their account. One caveat: most of the pricing above comes from third-party comparison sites, and APM list prices move often - confirm the current numbers on each vendor's own pricing page before you build them into a client quote.
